If you follow the same rules for the family bed as for a crib, you should be ok. IE -firm mattress, well fitting sheets, no pillow or blanket near the baby and plenty of room for you to sleep comfortably.
when our Lo was born, we had a new bed on order cause the old one was "dead" I REFUSED to let DH bring LO to sleep in the bed unless one of us was awake the whole time cause the old bed was too soft and the sheets popped off and rumpled too easy. with the new bed, which is a firm mattress, and well fitting sheets, I will let DH bring him in to snuggle if he wakes an hour or less before time to get up. I still dont feel like we have enough room so I dont sleep well when he's in the bed. but we also had a "Arm's Reach Co-Sleeper" - a pack n play with one side that folded down and strapped to your bed, so the baby was still in his/her own bed, but was still right there. I HIGHLY recommend that for anyone who wants them right there but worried about the family bed idea.
They also make little "beds" that actually lay on the bed that have firm sides etc that the baby sleeps in but is still cuddleable and on the bed with you. (often used for newborns traveling like adoptions from out of state)View Thread
